LOCK-HINGE.

SPECIFICATION formingpart of Letters Patent No. 394,605, dated December 18, 1888.

Application filed April 2, 1888.

"0 all whom it may concern:

Be it known that I, WILLIAM P. PATToN, a legal resident of Harrisburg,Dauphin county, Pennsylvania, and a citizen of the United States, residing temporarily at lVashington, in the District of Columbia, have invented certain new and useful Improvements in Lock- Hinges for Iindow Shutters, Blinds, or Gates; and I do declare the following to be a full, clear, and exact description of the invention,

l such as will enable others skilled in the art to l open locked position.

which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thercon,which form a part of this specification.

My invention relates to an improvement in lock-hinges that are adapted to secure window shut-ters, blinds, or gates in desired position.

The object of my present invention is to produce a hinge of the type mentioned which will lock a window shutteror blind in an open or partially-open position, the hinge being right or left handed, as desired.

A further object is to provide a lock-hinge which may be produced complete without employing cores in the molding operation, it being understood that the hinge is to be cast into form, using metal as a material.

A further object is to atford a light, strong, and neat lock-hinge which may be produced in quantity by ordinary methods of manufacture at a low initial cost.

lVith these objects in view my invention consists in certain features of construction and combinations of parts,which will be hereinafterV described, and pointed out in the claims.

Referring to the drawings making a part of this specification, Figure 1 is a side elevation in perspective of the loclehinge in an Fig. 2 represents the hinge in elevation, showing the working or joint portion in section. Fig. 3 is a side elevation of the complete hinge opened and with its locking parts released from connection, ready to swing and close the shutter or blind. Fig. 4 shows the hinge completely closed with Serial No. 269,401. (Model.)

Fig. (5 is a plan view in section of the lock-hinge, taken 011 the line a: 5c, Fig. S, showing the position assumed by the sliding pintle when the locking parts are separated and the movable leaf released to swing and close the shutter to which it is secured. Fig. 7 is a vicw in perspective of the fixed leaf of the hinge with the upper portion broken away. Fig. S is a bottom plan view of the fixed leaf or the half-section of the hinge which is secured to a window-casement. Fig. .Il is a plan view in section of a hinge in position on a shutter and window-caseinent, also indicating by an operators hand thc method of applying pressure to release thelock of the hinge and al low its loose leaf to rotate. Fig. l() is a front elevation in perspective of the hinge. Figs. l1 and 1i? show plan views of the hinge in cross-section, exhibiting the working parts adjusted to lock at an angle of forty-five degrees and ninety degrees, respectively. Figs. 13, 14, and l5 are views of parts of the hinge detached. Fig. 16 is a sectional elevation of a fixed leaf and an attached locking-plate, showing a modified means for securing the parts together. Figs. 17 and 1S show other modifications of the hinge.

Two hinges are employed on each shutter to swingingly support it, and as these are preferably made duplicates of each other it will only be necessary to give a detailed description of a single hinge.

A A are hinge-leaves provided with the usual countersunk holes for the reception of wood-screws to fasten them in place. The portion of the hinge of which A is the retaining-leaf is intended to be secured to the window frame or easement. It is extended laterally to produce a bracket-plate, A?, which is of such a relative length as to afford a proper base for a locking-plate, which will be more specically described. The bracketplate A2 has an integral ange or table, a, formed on its top edge7 this table lying in a horizontal plane when the hinge is in position for service.

It will be seen on inspection of Fig. 8 that Fig. 5 is a top plan 5o plate d, to afford a screw-hole, s. (See Fig. 7.)

The inner edge of the leaf A is integrally projected a short distance toward the hole 3 in the table ci, forming a rib that projectsA above the upper surface of this table, the terminal end of the rib being preferably cut V- shaped, as shown in Fig. 7, to form a lockingtoe, e, the use of which will be shortly explained.

Upon each side of the leaf A the table d is extended to form stiffening flanges or ribs f f so as to render the connected leaf and bracket-plate strong at their point of j unction and avoid the use of a bulk of metal to attain such necessary rigidity and cohesive strength. rlhe upper surface of the table d is level, and it is preferably rounded or ovate in form of its peripheral edge. Upon it is mounted the locking-disk B, which is shown detached from other parts in Figs. 13 and 15. As will be seen in these figures, the locking-disk B consistsof a circular disk of metal, with a conicalor` spherical protuberance, B', formed on its upper face, and from the center of this conical inclined plane a cylindrical pintle, D, projects vertically. The circular border-line fn, which terminates the conical baseV B' of pintle D, is of such a relative diameter to that of the locking-disk on which it is formed that a'lat circular track or rim, 0,'is produced between these curved border-lines.

At a point, r, on the top surface of the track 0 a gradual upwardl inclination is produced by a thickening of the material to afford a laterally-curved inclined plane, B2, that terminates in a shoulder, d, which is formed by an open slot or notch, h, that is cut in the peripheral edge of the locking-plate B at this point. The width of the slot h is determined bythe distance between the shoulder d and an opposite shoulder, d', that is the terminal edge of a similar inclined plane, B3, which is located on the track o. This shoulder d is preferably made slightly higher than the shoulder or terminal edge of the inclined plane B2.

It will be noticed that the inclined surface of `the conical base Br is extended downwardly between the shoulders d cl tothe point u at the lower edge of the Vplate B, (see Fig. 13,) so

' Y that a continuous inclined surface is afforded and 3 bounding one-fourth ofthe circumference of the circular locking-disk B. The locking-disk B is preferably secured in place by a set-screw, b, which is inserted through the perforation s in the table o and boss a into a central t-apped hole in the body of the locking-disk B, as shown in Fig. 2,; but other plans of connecting the parts may be used.

The leaf A is the one that is secured to the edge of the shutter near its lower end, which vin the hinge I have elected to describe, for

convenience, I prefer to so locate. I VIt is projected from the portion which is affixed to the shutter, so that a shallow box or recessed plate, C2, may be afforded which is given the lform substantially as shown in Figs. 2, 4, and

6. As will be seen, the edges of the recessed cavity in the leaf-extension C2 are vertical. and parallel, and are sloped from the outer edge of the face k, which is in the same plane with the surface of the leaf A.

The width from the edge if to the edge t (see Fig. 2) of the recess just mentioned is preferably made equal to twice the diameter of the pintle D, and the height of the same is somewhat greater than the length of the pintle from the crown of the conical base B to its upper extremity, to allow the recessed leaf to be moved toward the other leaf when theV two are connected by the pintle D. The'depth of the recess inthe leaf-exten sion C2 is slightly in excess of the half-diameter of the pintle D, and a cap-plate, C, (shown detached in Fig. 14,) which is recessed to exactly mate with the cavity made in the leaf-extension C2, is placed to cover it, the said plate having ears c, which are perforated to align with similar holes in the leaf-extension C2, so that the two pieces may be secured together by rivets, and thus provide a socket having a transverse diameter that will loosely fit the pintle D, while the width from t to t of this cavity C2 is sufficient to allow the pintle to slide from one of these edges, t, to the opposite one, t. (See Fig. 6.)

On the lower edge of the cap-plate C (see Fig. 14) a depending lug, C', is integrally formed, which is intended to fit into and interlockwith the notch or open slot h in the edge of the locking-disk B when the shutter is opened or partially opened, as the situation may require. The length, considered vertically, of the locking-lug C is such in proportionv to the height of the inclined plane B2 that when the lug is in the position shown in Fig. 4, where it rests upon the track-surface of the locking-disk B, the `leaf A and its attachments will be supported at a proper height to afford a clearance distance between the outer IOO IIO

IZO

lower edge, d2, of the socket-box C2 and the upper edgesof the shoulders d d, and in consequence the swinging leaf A may be readily revolved on the-foot of thelug C', and also on the lower edge of the socket-box C2, which will then have a contact with the inclined surface on the crown of the conical baseB. The

lower -inner edge of the socket-box C? is rounded oif to afford` a free entrance to the pintle D, and also provide a broader surface for contact of this socketbox with the crown of the conical base B.

In operation, if the shutter to which the hinge is attached is placed in a situation which will allow it to swing and nearly touch the vertical wall of the building, as shown in Fig. 9, the locking-disk B is placed so that its notch or serration l is so located, relatively, that the locking-lug C will engage the notch h in the locking-disk B when the two leaves A A are in the same or parallel planes nearly coincident. Then the parts are adjusted as stated, the shutter, if closed and thrown open by pressure of the hand of an operator against its inner surface, will by its momentum cause the locking-lug C to move up the inclined plane B, and when it is in a position above the notch 71 the lug will drop into the notch with which it is adapted to mate, and thus lock the shutter in an open position close to but not touching the wall of the building'.

It should be explained that the notch h is tapered slightly, the side walls or shoulders, d d', rendering it wider at the top than at the bottom, which will facilitate the withdrawal of the locking-lug C when it desired.

lVhen the shutter is to be closed, the hand is applied to the outer surface of the shutter near the lower hinge, as shown in Fig. 9, in which O represents the shutter in open position, P the wall of a building, G the window-casing, and R the hinge in section. If the fingers of the operator are now pressed with moderate force inwardly, the leaf A and the attached shutter willV be caused to move upwardly and inwardly by reason of an engagement of the lower end of locking-lug C with the inclined surfaces of the conical base B at this point. As has been previously shown, the sloping surfaces of this conical base extend downwardly between the shoulders d d, so as to permit the engagement of the locking-lug C in the manner just mentioned. XYhen the shutter is pressed to slide as just stated, the pintle D will resume the position shown in Fig. 9, and by a simultaneous inwardly-swinging movement in the direction of the arrow the shutter will be readily closed.

As all the weight of the shutter is made to bear on the lower edge of the socket-box C2 and the locking-lug C', this lug will be held in close contact with the conical base B at its lower portion, and thus draw the socketbox on the side opposite the lug C against the pintle, so that a smoothly-working joint without rattle is thus afforded, the joint being held from lateral motion throughout its entire swinging movement when a shutter is opened or closed.

Should it occur that the shutter cannot swing entirely open by reason of obstructionssuch as walls or fencespreventing the same, a lock may be effected at an angle of forty- Iive degrees, or at a right angle with the wall P, instead of' parallel to it, as has been explained, by first relaxing the screw I), which is used to secure the lockingedisk B upon the table a, and shifting the disk to bring the V- shaped notch 2 into line with toe e, and then clamping the pieces together by th e screw l), if an angle of forty-five degrees is desired, or into the notch I3, if a right angle or ninety degrees removal of the shutter from the wall l is necessary.

It is obvious that other notches may be cut in the edge of the disk B to afford means for changing the locking-point of the hinge to a different angle than those shown; hence I do not wish to limit myself to three notches.

In Fig. lt a modified form for a revoluble engagement of the locking-disk B with the table a or bracket-plate A2 is shown. rlhis consists in the provision of an integral depending pintle, p, which is inserted through a neatly-fitting hole formed in the table (L and boss a', this pintle taking the place of a setscrew, b, and may be employed in somehinges where a sufficient weight of shutter is imposed upon the locking-disk to retain it in place, it being understood that the notches l 2 $3 and locking-toe e are utilized, as has been previously explained.

The locking-notches 1 2 il may be dispensed with and spaced perforations made in the table (l, which are adapted to receive a depending pin formed on the under side of the locking-disk, thus affording a similar lock in substantially the same manner as is effected by the V-shaped notches 1 2 3 and locking'- toe e.

In Figs. 1T and 18 are shown views of another slightly-lnodified form of the hinge, whereby it is adapted for use as a right and left hand hinge at will. Fig. 17 is a side elevation of the leaf which is affixed to the window-casing, the working parts attached thereto being in section taken through the axial center of the pintle, the remaining figure (18) representing' a front elevation in section of the parts taken on the line y fg, Fig. 17. The boss ct of the bracket-plate A2 is widened laterally, as shown in Fig. 18, and is located at its center of width on the bracket-plate A2. This construction of parts will allow the depending small pintle p, which is formed on the lower side of the locking-disk B, to engage either one of the parallel vertical perforations p', made in the boss a', and thus locate the upper pintle, D, to the right or left of a centerline, to afford folding action on either side of the leaf A, and thus produce a right or left hand hinge.

If the hinge is made to fold in either direction, so as to suit right or left hand shutters, it will be necessary to countersink the screwholes in the leaves on both sides, as is shown, the material being thickened up around the holes on each side of the leaves to admit this without making the whole leaf heavy enough to allow countersinks to be so formed.

By a reversal of the locking-disk B with re IOO IIO

l gard to the su inging leaf A and changing the position correspondingly of the locking' which may be effected by an edgewise press ure applied to the gate in an obvious manner.

It is feasible to produce the socl etbox and the leaf A integral with each other by use of a core; but I prefer to form the socket-box eniploying the capplate C, as this method of construction allows the hinge to be made without the use of a core by snap-flask molding, such as is commonly employed in the manufacture of light hardware in small pieces.

Other minor changes may be made in the details of construction of the hinge without exceeding the scope of my invention; hence I do not desire to restrict myself to the exact forms herein shown; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination, with a hinge-leaf having a pintle and a locking-disk removably secured to said leaf, and having a slot therein, of a mating leaf having an elongated socket adapted to receive the pintle and a lockinglug to enter the slot, substantially as set forth.

ing a pintle, a conical base to the pintle, and a locking-disk, of a mating leaf having an elongated socket and a locking-lug, substantially as set forth.

4. The combination, with a hingefleaf having an integral bracket-plate and a locking device attached to the bracket-plate, and a circular locking-disk having an integral pintle, inclined planes, the separated shoulders of which produce an open slot between them, and provided with spaced notches that are made to engage a locking-toe, of a mating hinge-leaf bearing an elongated socket-box, the walls of the socket being parallel to allow sliding motion on the pintle, substantially as set forth.

5. The combination, with a hinge-leaf hav` versely considered, of a locking-disk which is provided with an upwardly-projected pintle and a depending pintle located in the same vertical plane, a device attached to the locking-disk and hinge-leafto lock the disk at` any desired point, rotatively considered, a mating hinge-leaf having a verticalA socket which has parallel walls and is elongated laterally to engage slidingly with the main pintle of the other leaf, and a depending lockingtoe secured to said leaf, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
